Overview
- The partial eclipse is set for Wednesday, August 12, with London’s spectacle beginning around 6:17pm, peaking at about 7:12pm and ending near 8:06pm, and local peak coverage ranging roughly 90–96 percent depending on location.
- Totality will occur only along a narrow path crossing parts of Greenland, Iceland, northern Russia and northern Spain, so the UK and Ireland will see a deep partial eclipse rather than full darkness.
- Authorities and observatories stress eye safety for the whole event, advising use of ISO 12312‑2 certified solar viewers or indirect projection and warning that ordinary sunglasses, damaged filters or unfiltered optics are unsafe.
- Coordinated science efforts are underway, including an Irish Air Corps flight carrying DIAS staff to image the solar corona, NASA airborne observations over the North Atlantic, high‑altitude balloons and multiple observatory livestreams to guarantee cloud‑insured views.
- Public demand has driven many sold‑out local events and pressure on certified eclipse‑glass supplies, and organisers warn that low sunset angles and any western horizon obstruction or cloud could fully spoil in‑person viewing despite otherwise favourable forecasts.
